Inelastic Dynamic Finite-Element Design of Light Gauge Metal Stud Façade Systems for Blast Loading
Exterior façades being designed for dynamic blast loadings traditionally have used cast-in-place concrete, precast concrete or reinforced concrete masonry unit construction. These systems, although very effective in resisting blast loading, can add substantial weight and cost to the building's structure. Light gauge metal stud façade systems are commonly used in conventional construction projects because they are relatively light weight, cost effective, and can be constructed in unitized systems pre-fabricated off-site thus minimizing erection and building enclosure schedules. Due to these benefits, their use is becoming more prevalent in blast resistant applications. Light gauge metal stud systems can be designed for blast loads using traditional single degree of freedom (SDOF) dynamic analysis techniques; however, inelastic dynamic finite element modeling (FEM) tools can be used to optimize the design of these flexible and ductile systems, particularly for more complex wall geometries and systems with multiple connected components. Finite element models can provide a more in-depth understanding of the overall wall system behavior, the interaction and phasing of the system components and the sensitivity of the system to variations of connected elements and span lengths.
